I was struggling to live with the popping and choking form my stock exhaust. I figured I would start by adding new pipes Well, I finally put my Vance and Hines Big Radius 2:2 onto my 04 mastiff. When I took the stock exhaust off the the bike, there was a split in the header where the 2 went into 1 (at the weld). Needless to say, I was pissed. I added the new exhaust and it runs like a bat out of hell and no popping or choking. So, if you are having trouble with your stock exhaust, check it!!! I'll post pics soon!!!
